As the thread opener from lead designer Darrin McPherson explains, sometimes as a developer it's hard to see what a game is missing simply because you're too close to the game. You know how all the systems work; you built most of them, after all. Players, on the other hand, can find holes in explanations that might otherwise be unavailable. If you've been playing around in the test and want to add your thoughts, head over to the official thread and let the team know what's intuitive and what isn't.
